Encrypted Messenger for iOS and Android

  • ChatSecure on iOS App Store
  • ChatSecure for Android on Google Play

What is ChatSecure?

ChatSecure is a free and open source messaging app that features OTR encryption over XMPP. You can connect to your existing accounts on Facebook or Google, create new accounts on public XMPP servers (including via Tor), or even connect to your own server for extra security.

Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OTR and XMPP, such as Adium, Jitsi, and more.

Strong Cryptography

ChatSecure only uses well-known open source cryptographic libraries to keep your conversations private. Other apps may make claims about "military grade" security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.

Free and Open Source

We believe in the power of free and open source software. The full source code to the iOS and Android apps is available on GitHub.
